How to pin a version of specific package?

[aborzunov]

Different versions of clang-format can produce different formatting results even with the same .clang-format configuration, which makes formatting non-deterministic across environments. This becomes an issue when working in teams or CI environments...

Is there a way to pin a specific version of a package (e.g., clang-format) without pinning the entire Mason registry?

More generally, does Mason support per-package version pinning, or is freezing the registry the only available approach?
